+Implemented Support for Custom Docker Image Labels in GitHub Actions Workflow:
+
+Incorporated functionality to seamlessly manage custom labels for Docker images within the GitHub Actions workflow. The enhancements were made as follows:
+
+1. **Enhanced Action Configuration (`action.yaml`):**
+   - Introduced the `imageLabels` parameter in the Docker build action configuration.
+   - The `imageLabels` parameter empowers users to define custom labels for Docker images during the build process.
+2. **Improved Workflow Configuration (`nightly.yaml`):**
+   - Introduced the `imageLabels` parameter in the workflow configuration.
+   - Illustrative usage: Setting `imageLabels: quay.expires-after=14d` to specify a 14-day expiration for images.
+   - When executing the nightly workflow, the Docker image will be enriched with the designated labels.
+
+**Usage Guide:**
+To leverage the new `imageLabels` parameter, navigate to the workflow configuration (`nightly.yaml`) and modify the `imageLabels` parameter as needed:
+
+```yaml
+jobs:
+  release:
+    ...
+    steps:
+      ...
+      - name: Publish
+        uses: ./.github/actions/docker-build
+        with:
+          ...
+          imageLabels: "quay.expires-after=14d" # modify this
+          push: true
+
+```
